### Product Overview: CSTCC3M58G53A-R0 The **CSTCC3M58G53A-R0** is a specific model of a **Ceramic Resonator** manufactured by Murata Manufacturing Co., Ltd. It belongs to the CERALOCK® family, which are components used to provide a stable clock frequency for microcontrollers, microprocessors, and other digital circuits. --- ### 1. Key Technical Specifications | Parameter | Specification | Details | | :--- | :--- | :--- | | **Nominal Frequency** | 3.58 MHz | Standard NTSC color burst frequency. | | **Frequency Tolerance** | ±0.5% | Initial deviation from nominal frequency. | | **Built-in Capacitance** | 15 pF | Includes internal load capacitors (CL1/CL2). | | **Mounting Type** | Surface Mount (SMD) | Designed for automated PCB assembly. | | **Temperature Range** | -20°C to +80°C | Standard operating range. | | **Package Size** | 7.2 x 3.0 mm | Standard "CSTCC" footprint. | --- ### 2. Functional Characteristics #### A. Internal Structure (Built-in Capacitors) Unlike traditional quartz crystals that require external load capacitors to start oscillating, the "CSTCC" series includes **built-in load capacitors**. - This reduces the component count on the PCB. - It saves physical space and simplifies the circuit design. #### B. Piezoelectric Effect It operates on the principle of the piezoelectric effect. The ceramic material mechanically vibrates at a specific frequency when an electrical signal is applied, acting as a highly stable band-pass filter or timing source. #### C. Stability vs. Crystals - **Ceramic Resonators:** Offer faster start-up times and are generally more cost-effective and physically rugged. - **Quartz Crystals:** Offer much higher frequency precision (PPM vs percent), but are more fragile and require more power. --- ### 3. Pinout and Connection The device typically features **3 terminals**: 1. **Input (1):** Connected to the XTAL/OSC input of the MCU. 2. **Ground (2):** The middle pin, connected to the system ground (shared by internal capacitors). 3. **Output (3):** Connected to the XTAL/OSC output of the MCU. --- ### 4. Common Applications - **Microcontrollers:** Providing the "heartbeat" for 8-bit or 16-bit MCUs. - **Consumer Electronics:** TV remote controls, toys, and household appliances. - **Legacy Video Gear:** Because it operates at 3.58 MHz (NTSC frequency), it was historically common in video encoding hardware. ---
